im looking to replace a webserver and a freenas box with possibly one low power itx setup.

At the moment ive got a dell rackmount server sucking up the grid running esxi and an old p4 running freenas which sounds like it taking off - they both work great! but I need to cut down on power usage and also the noise!!. :(

I wouldnt mind somthing I could run esxi on as well ? - so maybe I could run a couple of vms? no idea if this bit is possible.

.....dont need any cd drives or gfx cards etc, from what ive read I dont think a realtek nic is compatible with esxi...only intel.

Any ideas on hardware? is nas / webserver possible on same box? neither will be under heavy use. I will be doing the odd backup to the nas.

thanks for your help in advance, any pointers would be great. I have looked the stand alone nas's reviews and they are either too much £££ or tempermental - I think performance would be a lot bettr fro somthing home built.
